Australian Grand Prix could be postponed because of Covid-19 restrictions in Australia.
A final call on staging the Australian Grand Prix will be made in the “coming weeks”, organisers said.
It is due to take place in Melbourne from 19-21 March. Tickets for the race at Albert Park have yet to go on sale.
Many of Formula One’s teams are also based in England where cases are surging, spurred by a more infectious new variant, further complicating matters.
The Bahrain GP, set for March 28 was set to be the second race of the new season but now is poised to replace Australia as the season-opener.
Local organisers in Melbourne were not immediately available for comment, but various reports said a postponement, rather than a cancellation for the second year in a row, was likely to be announced later in January.
Australia continues to maintain strict quarantine rules on international arrivals.
Last year’s Australian Grand Prix was called off, only hours before first practice was due to start, when a McLaren team member tested positive for coronavirus.
